Quantum Sensors Group Members

The Group focuses on:

  • quantum effects, including superconductivity;
  • low temperatures to reduce thermal noise; and
  • the development of advanced sensors.

Major activities of the Group include:

  • superconducting x-ray and gamma-ray spectrometers for applications that include materials analysis and nuclear materials accounting
  • superconducting microbolometers for applications that include concealed weapons detection and understanding the early universe 
  • advanced cryogenics to aid the dissemination of cryogenic sensors
  • the determination of x-ray fundamental parameters to facilitate materials analysis by x-ray techniques
  • support of U.S. industries that develop or use advanced cryogenics and cryogenic sensors
